The Negative Impact of Ultra-Processed Foods on Muscle Health, Despite Regular Exercise

The Dangers of Ultra-Processed Foods: How They Can Affect Muscle Quality

A new study presented at the Radiological Society of North America annual meeting has shed light on the negative impact of consuming ultra-processed foods on muscle quality. Ultra-processed foods such as sodas, snacks, and frozen meals have already been linked to metabolic syndrome, type 2 diabetes, and certain cancers. Now, researchers have found that these foods could also lead to increased fat within thigh muscles, which can have serious implications for movement and overall health.

According to the study’s lead author, Dr. Zehra Akkaya, previous research has shown a connection between a “Western” diet high in ultra-processed foods and poor knee health. This prompted the team to delve deeper into how these foods affect muscle quality, specifically in relation to knee osteoarthritis.

The study, which analyzed data from over 600 participants at risk for knee osteoarthritis, found a significant relationship between higher consumption of ultra-processed foods and poorer thigh muscle quality. The more ultra-processed foods a person consumed, the higher the level of fatty tissue relative to healthy muscle tissue within their muscles.

While the study only shows an association and not causation, experts suggest that reducing the intake of ultra-processed foods could help prevent the development of intramuscular fat. Additionally, focusing on a healthy diet rich in protein, fiber, and healthy fats, as well as regular exercise, can help maintain muscle quality and overall health.

The findings of this study highlight the importance of being mindful of the foods we consume and their impact on our muscles and overall well-being. By making conscious choices to limit ultra-processed foods and prioritize a nutrient-rich diet, we can support our muscle health and reduce the risk of chronic diseases like osteoarthritis.
